Cannabis

The average age of introduction to cannabis consumption is 15-17 years, and the duration of abuse is, on average, 6-7 years [1].

Dronabinol. Marinol ( ii7R-/n7 j )-6i7,7,8,I0i7-tetrahydro-6,6,9-trimethyl-3-pentyl-6JT-diben2o(B,D) pyran-I-ol is the principal psychoactive substance present in Cannabis sativa F., ie, marijuana. It is a controlled substance, formulated in sesame oil and encapsulated in soft gelatin capsules for oral adrninistration. 

Pharmacological Profiles of Anxiolytics and Sedative—Hypnotics. Historically, chemotherapy of anxiety and sleep disorders rehed on a wide variety of natural products such as opiates, alcohol, cannabis, and kawa pyrones. Use of various bromides and chloral derivatives ia these medical iadications enjoyed considerable popularity early ia the twentieth century. Upon the discovery of barbiturates, numerous synthetic compounds rapidly became available for the treatment of anxiety and insomnia. As of this writing barbiturates are ia use primarily as iajectable general anesthetics (qv) and as antiepileptics. These agents have been largely replaced as treatment for anxiety and sleep disorders.

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. 

Nabitan (39) is a cannabis-inspired analgesic whose nitrogen atom was introduced in order to improve water solubility and perhaps to affect the pharmacological profile as well. The phenolic hydroxyl of benzopyran synthon is esterified with 4-(l-piperidino)butyric acid under the influence of dicyclohexyl carbodi mi de. In addition to being hypotensive and... 

A sesquiterpene has been isolated from the essential oil of Cannabis Indica. This may fairly be considered a definite body, as it has been isolated by many different observers and described by them at different times. Valenta first mentions it. Vignolo describes it as a mobile liquid boiling at 256°, of specific gravity -897 at 15°, and slightly laevo-rotatory. Wood, Spivey, and Easterfield give the boiling-point as 258° to 259°, the specific gravity as -898 at 18°, and the rotation as - 8-6°. 

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...

Group of compounds which naturally occur in the hemp plant, Cannabis saiiva. Most of them are unsoluble in water. The most abundant cannabinoids are A9--tetrahydrocannabinol (THC), its precursor cannabidiol and cannabinol, which is formed spontaneously from THC. Cannabinoids exert their effects through G-protein coupled cannabinoid receptors (CBi/CB2). 

The plant Cannabis sativa produces the psychoactive diug A9-tetrahydrocannabinol (THC). Recreationally, THC is consumed in form of marijuana (dried flowers and leaves) or hashish (resin). The cultivation and possession of Cannabis for recreational use is not... 

Dronabinol (tetrahydrocannabinol), the active principle from cannabis and synthetic cannabinoids, nabilone and levonantradol are effective in treating nausea and vomiting in cancer chemotherapy. The mode of action is unclear but appears to involve cannabinoid CBi receptors. Cannabinoids have been shown to reduce acetylcholine release in the cortex and hippocampus, and have been suggested to inhibit medullary activity by a cortical action. Inhibition of prostaglandin synthesis and release of endorphins may also be involved in the antiemetic effect. A review of trials of dronabinol, nabilone or levonantradol concluded that while the cannabinoids were superior to placebo or dopamine receptor antagonists in controlling emesis... 

Endocannabinoids. Figure 1 Chemical structures of the two most studied endocannabinoids, anandamide and 2-arachidonoylglycerol, of Cannabis sativa psychoactive principle, A9-tetrahydrocannabinol, and of the CB-i receptor antagonist/inverse agonist, rimonabant. 

Based on the role of endocannabinoids and cannabinoid receptors in several pathological conditions, the pharmacological manipulation of their levels or action is being developed as a therapeutic strategy. Enhancement of endocannabinoid signalling when this plays uniquely a protective role can be effected in a safer way using (i) cannabis extracts in which the presence of non-psychotropic cannabinoids with therapeutic activity per...

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). 

These prevalence estimates, however, obscure an ongoing controversy surrounding the nature of the cannabis dependence syndrome. Specifically, the studies cited earlier, which were designed to examine the prevalence of abuse...
