Cannabis

“ The psychoactive effects of cannabis, principally mediated by THC, occur via its interaction with the endocannabinoid system, which regulates numerous biological processes involved in development and neuroplasticity. ”

“ Cannabis use is associated with progression to use other illicit substances in humans. Twin-studies illustrate that cannabis users have an increased risk of developing substance abuse disorder compared to their discordant twin. ”

“ Cannabis and Developmental Pattern of Use
Psychiatric illnesses are developmental in nature – the 12-month prevalence of any psychiatric illness is ∼40% in adolescents ( [2] ) , but ∼25% in adults ( [3] ) – making it significantly germane to the strong developmental pattern of cannabis use. A plethora of studies and national surveys monitored the patterns of cannabis use in multiple ethnic and geographic populations worldwide. In the United States, cannabis use is highly prevalent during adolescence (Figure 1) , the developmental period when most people initiate use. ”

“ Risks Associated with Usage of Cannabis 4.1. Psychiatric Manifestations Arising from the Usage of Cannabis There are various psychiatric manifestations that might arise from the usage of cannabis. Anxiety disorders have been reported to be associated with cannabis usage. A recent meta-analysis [8] that looked at 31 studies involving 112,000 individuals has found a positive association between anxiety disorder and cannabis usage. It is postulated that individuals with underlying anxiety disorders might have used cannabis as a form of self-medication to help them cope [9] . ”

“ Cannabis sativa produces an intoxicant that in Turkey is known as hadschy, in Arabia and India as hashish, and to the Hottentots as dacha, and serves as a drunkard's food in other lands. The fruit of the juniper produces gin, and the fermented juice of the grape, or malt liquors, in all civilized countries are the favorite intoxicants, their origin being lost in antiquity. ”

“ The most common method used to consume cannabis is via smoking the product, but it might also be consumed orally in various food products [5] .
2. Pharmacology of Cannabis Understanding the pharmacology of cannabis is essential as it helps to understand the side effects associated with cannabis and its proposed medical benefits. The main constituent that is responsible for the psychoactive properties is tetrahydrocannabinol [6] . In the central nervous system, there are 2 main subtypes of the cannabinoid receptors. These receptors are commonly known as cannabinoid-1 and cannabinoid-2 [7] . ”

“ The high prevalence of cannabis use among teens and the increasing number of states in the USA that legalize cannabis for both medicinal and recreational purposes are concerning given the surprisingly limited information known about the impact of cannabis on the developing brain and individual susceptibility. ”

“ When given in full doses, cannabis Indica produces a feeling of exhilaration, with a condition of reverie, and a train of mental and nervous phenomena, which varies very much according to the temperament or idiosyncrasies of the subject, and very probably also, to some extent, according to the nature of his surroundings. The sensations are generally spoken of as very pleasurable; often beautiful visions float before the eyes, and a sense of ecstacy fills the whole being ”

“ These effects usually last for 2 to 4 hours. However, the effects of cannabis on cognition might last much longer, ranging from 5 to 12 hours. Those who consume cannabis orally might not experience such significant symptoms as the bioavailability is significantly reduced. Individuals who have consumed high doses might be acutely confused, and they might have other clinical symptoms such as hypotension and hypothermia as well as psychiatric manifestations such as psychosis. ”

“ Twin-studies, which control for potential confounds such as genetics and shared environmental influences, have also confirmed that early adolescent onset of cannabis use increases the likelihood of developing drug dependence later in life ( [22] ) . ”

“ Numerous human studies, including prospective longitudinal studies, demonstrate that early cannabis use is associated with major depressive disorder and drug addiction. A strong association between schizophrenia and cannabis use is also apparent, especially when considering genetic factors that interact with this environmental exposure. These human studies set a foundation for carefully controlled animal studies which demonstrate similar patterns following early cannabinoid exposure. ”

“ Illicit drugs:
illicit producer of cannabis for the domestic drug market and export to US; use of hydroponics technology permits growers to plant large quantities of high-quality marijuana indoors; increasing ecstasy production, some of which is destined for the US ”

“ The first longitudinal studies demonstrating an association between cannabis use before adulthood and schizophrenia were conducted in Swedish conscripts ( [50] , [51] ) Although no information was known about the individuals before conscription, subjects reporting previous cannabis use at the time of conscription were significantly more likely to be diagnosed with schizophrenia later in life. ”

“ Tinctura Cannabis (Tr. Cannab.) , Tincture of Cannabis, U.S.P. (Tinctura Cannabis Indicae, U.S.P. VIII) .—Cannabis (10%) in alcohol. Assayed biologically by producing incoordination in dogs. Absolute alcohol content about 90 per cent.
Dosage: 0.75 Cc. or 12 minims (U.S.P.) . Those physicians who prescribe tincture of cannabis should specify the biologically assayed preparation.
*Cantharis (Canthar.) , Cantharides, U.S.P. (Spanish Flies, Russian Flies) .—A beetle.
Action and Uses: Externally, rubefacient and vesicant. Internally, genito-urinary irritant, often producing serious nephritis. ”

“ I am aware how incredible this statement will seem to those who have never had any extensive experience of the behavior of this remarkably variable drug, and get their notion of its action from the absurd directions on the label of every pound vial I have seen sent forth by our manufacturing pharmaceutists. "Ten to twenty drops at a dose," they say, "cautiously increased." Cannabis should always be used with caution, but ten or even twenty drops must be inert in all but the rarest cases, and I have given an ounce per diem with beneficial effect. ”

“ I once told Frank Merrill, many years ago, when I was very enthusiastic, that an infusion of cannabis indica, combined with tincture of opium and hyocine, produced certain effects."
"It is inclined to sap the will power of a man or a woman who is constantly absorbing this poison in small doses?" suggested the counsel. ”

“ Excessive indulgence in cannabis indica is very rare, but may lead to general ill-health and occasionally to insanity. The apparent impossibility of obtaining pure and trustworthy samples of the drug has led to its entire abandonment in therapeutics. When a good sample is obtained it is a safe and efficient hypnotic, at any rate in the case of a European. The tincture should not be prescribed unless precautions are taken to avoid the precipitation of the resin which follows its dilution with water.

I Illicit drugs
This entry gives information on the five categories of illicit drugs - narcotics, stimulants, depressants (sedatives) , hallucinogens, and cannabis. These categories include many drugs legally produced and prescribed by doctors as well as those illegally produced and sold outside of medical channels. Cannabis (Cannabis sativa) is the common hemp plant, which provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer) , tetrahydrocannabinol (THC, Marinol) , hashish (hash) , and hashish oil (hash oil) . ”

“ Hashish is the resinous exudate of the cannabis or hemp plant (Cannabis sativa) .
Heroin is a semisynthetic derivative of morphine.
Mandrax is a synthetic chemical depressant, the same as, or similar to Quaalude.
Marijuana is the dried leaves of the cannabis or hemp plant (Cannabis sativa) .
Narcotics are drugs that relieve pain, often induce sleep, and refer to opium, opium derivatives, and synthetic substitutes. Natural narcotics include opium (paregoric, parepectolin) , morphine (MS-Contin, Roxanol) , codeine (Tylenol with codeine, Empirin with codeine, Robitussan AC) , and thebaine. ”

“ Whenever the prevailing conditions in the country or a territory of a Party render the prohibition of the cultivation of the opium poppy, the coca bush or the cannabis plant the most suitable measure, in its opinion, for protecting the public health and welfare and preventing the diversion of drugs into the illicit traffic, the Party concerned shall prohibit cultivation. ”

“ Illicit Use of Cannabis and Legislation in Singapore In Singapore, cannabis has been included as a Schedule 1 drug in the 1961 Single Convention on Narcotic Drug [51] . Singapore is one of the countries amongst 184 countries to have signed this agreement to curb the cultivation of the plant. In Singapore, there are grave legal penalties associated with the abuse or possession of cannabis. Individuals are liable to be fined up to 20,000 Singapore dollars or be imprisoned for up to 10 years if they are found to have consumed or found to be in possession of the drugs [51] . ”

“ Based on the current evidence available from human and animal models, it is evident that cannabis use during adolescent development increases risk of psychiatric diseases such as drug addiction and schizoaffective disorders with genetic interactions. No convincing data exist to support one “common cause” that exclusively predicts which individuals using cannabis as teens will progress to addiction and psychiatric disorders later in life versus those who do not. ”

“ III of the National Longitudinal Study for Adolescent Health recapitulate this pattern of wide spread yet occasional use in adolescents. While the majority of teens have infrequent use, still a significant percentage, 6.6%, report daily use. Determining the long-term impact of occasional and heavy cannabis use during active periods of brain development, such as adolescence, is of critical importance. ”

“ Neurosine being a harmless remedy is especially indicated for neurotic individuals.”
Apart from cannabis indica, Neurosine contains no efficient hypnotic. Cannabis indica is a dangerous drug, whose administration to “neurotic individuals” is by no means free from danger—​especially when it is given under a proprietary name that carries no warning of its presence.
Here is another recommendation—this time for chorea:
“All authorities recommend the bromides, hyoscyamus and cannabis indica in this disease. ”

“ The legal penalties for illegal trafficking of the drug are even more severe. Individuals will face the death sentence if they import or export cannabis of more than 500 grams, resin of more than 200 grams, or mixture of more than 1000 grams. ”

“ If we are successful we shall ere long present it to the medical profession. With all the objections that prejudice cannabis now, I have still witnessed repeated proofs of its great value in lulling pain and procuring sleep, when all other means had failed with the reforming opium-eater, in doses of from one drachm to five of fluid extract or tincture (in some rare cases even larger) , administered twice a day. Like opium it is only secondarily a soporific, and to produce this effect it should be given three or four hours before the intended bed-time. ”

“ The pure alkaloid, cannabin, has been recently introduced as a soporific, in doses of three-quarters of a grain to a grain and a half. According to Stillé and Maisch, the wakefulness caused by the itching of eczema may be relieved by the use of cannabis indica. The uneasy sleep attendant upon ungratified sexual appetite may also be relieved in the same way, since the drug is decidedly anti-aphrodisiac. ”

“ Consequently, THC and related compounds could potentially usurp normal adolescent neurodevelopment, shifting the brain’s developmental trajectory toward a disease-vulnerable state, predisposing early cannabis users to motivational, affective, and psychotic disorders. ”

“ Were we able to procure a thoroughly reliable extract of hemp in this country, and did physicians use it as freely, as carelessly, and in as large doses, as they are using opium, morphine and chloral, hashisch takers would be more common.
Known in English-speaking countries as Indian Hemp or Cannabis Indica, it is called Hashisch by the Arabians, Gunjah and Churrus by the inhabitants of India, Bust or Sheera by the Egyptians, Dagga or Dacha by the Hottentots, El Mogen by the Moors. This is the solid extract. Bangue, Bang or Bendji is the spirituous extract. ”

“ Motivation and cognition may be altered, making the acquisition of new information difficult. Marijuana can also produce paranoia and psychosis.
Because users often inhale the unfiltered smoke deeply and then hold it in their lungs as long as possible, marijuana is damaging to the lungs and pulmonary system. Marijuana smoke contains more cancer-causing agents than tobacco.
Long-term users of cannabis may develop psychological dependence and require more of the drug to get the same effect. The drug can become the center of their lives. ”

“ Cannabis, or Indian hemp, either the same species from which the far-famed haschish of the East is made, or very closely allied to it. They always choose a rich and moist soil on the sunny side of a hill, as the plant requires both heat and moisture to attain perfection. The natives seem to prefer their liamba even to the tobacco; but there are some doubts whether both these plants have not been imported, the tobacco from America and the liamba from Asia, or more likely from north-western Africa. Du Chaillu says that the Ashira and Apingi are the only tribes who cultivate it. ”
