Cannabis drugs

CANNABIS DRUGS OF ABUSE -COCAINE Quickens the onset of effects of cocaine and t bioavailability of cocaine, leading to enhanced subjective effects of cocaine (e.g. euphoria), and t heart rate and other cardiac effects such as ischaemia Attributed to cannabis-induced vasodilatation of the nasal mucosa, which leads to t absorption of cocaine Be aware. May be the cause of ischaemic cardiac pain in young adults... 

Marij uana/hashish These are cannabis drugs that seem to act as a CNS depressant. The effects are mental relaxation, euphoria, and decreased inhibitions. 

When challenged, these statements were never supported. Dr. M. V. Ball, one of America s few authorities on marihuana, visited the border towns in 1922 as a representative of the American Medical Association to get a firsthand look at the alleged dangers of marihuana to the citizenry. Ball had previously noted that whenever cannabis drugs were mentioned in the old scientific literature, they were invariably mixed with opium, and he was sceptical of the reports he had heard about the drag as far as its criminogenic properties were concerned.

However the gastroduodenal phytotherapy has not developed in a similar way. In the past century, opium extract was frequently used in the treatment of severe pain associated with peptic ulcer disease. Other sedative remedies prescribed included belladonna, hyosciamus, connium, and cannabis, drugs with analgesic or anticholinergic properties.

Cannabinoids were used in medicine in the form of their crude extracts many centuries ago. Lately the use of cannabis for so-called recreational purposes has become a national vice of substantial proportions. Several attempts have been made to focus the potentially useful pharmacological properties of marijuana into drug molecules with no abuse potential. 

There are some specific differences between the cubic and extended ternary complex models in terms of predictions of system and drug behavior. The first is that the receptor, either ligand bound or not bound, can form a complex with the G-protein and that this complex need not signal (i.e., [ARiG] and [RjG]). Under these circumstances an inverse agonist (one that stabilizes the inactive state of the receptor) theoretically can form inactive ternary complexes and thus sequester G-proteins away from signaling pathways. There is evidence that this can occur with cannabi-noid receptor [26]. The cubic ternary complex model also... 

Comparable findings for lifetime prevalence of psychiatric disorders were obtained in another study of 133 persons, which also found that 47% received a concurrent DSM-III diagnosis of substance abuse or dependence (Khantzian and Treece 1985). The most frequently abused substances were sedative-hypnotics (23%), alcohol (14%), and cannabis (13%). Similar rates of psychiatric disorders were found in other studies of drug abusers (Mirin et al. 1986 Woody et al. 1983). Although such diagnoses do not imply causality, and, in many cases, opioid dependence causes or exacerbates psychiatric problems, some causal link seems likely (Regier et al. 1990).

Anticholinergics used in gastrointestinal disorders Over-the-counter antiasthma drugs Note. Cannabis not included here. 

Inexperienced users or individuals who are exposed to the drug unexpectedly (e.g., who unknowingly consume PCP-adulterated cannabis) may develop severe anxiety and panic because of the intensity and variety of symptoms. Perceptual distortions have sometimes led to extremely violent behavior, accidents, or self-damaging acts. An especially high risk of violent behavior has been reported in acutely intoxicated PCP users who have a history of psychiatric problems. Intoxication with doses in excess of 150 mg may lead to convulsions, coma, and death from respiratory arrest. Other complications include hypertensive crisis, intracerebral hemorrhage, and renal failure (Table 6-5). 

True. Whilst many drugs prescribed by a doctor can be very good for your health, there are many others that can be very harmful to your health, e.g. heroin, nicotine, cannabis, etc. It should be remembered that even medicinal drugs prescribed by the doctor can be harmful if misused. 

Cannabis is an illegal drug and potentially very harmful to health, particularly that of young people. 

True. Cannabis is a depressant drug. One of its effects is to slow you down psychologically (slows brain activity) and, as a result, physically. 

False. Cannabis is a depressant drug which achieves its effects by slowing brain activity. This slows the user down both psychologically and physically.
