...classify the dangers of marijuana as on a par with those of alcohol. However, so far there is no scientific evidence on whether long-term use can produce effects comparable to alcohol's cirrhosis or tobacco's cancer and emphysema. Marijuana's active ingredients?chemicals known as tetrahydrocannabinols (THC)?can cause LSD-type psychotic hallucinations when administered in pure form. (Such a reaction can happen considerably more easily with hashish, a concentration of dried Cannabis resins some six times as powerful as marijuana.) Pot affects the sense of time, but not motor and perceptual skills...
...THC, commonly known as "synthetic marijuana," is one compound isolated from marijuana, but it has never been proven as the active compound, Dr. Weil said, "and there is no such thing as illegal THC. That is just tranquilizer in a capsule. The real stuff is too hard to get and too expensive to manufacture illegally...
...users know whether or not they are getting real THC? "If it doesn't cost at least $15 a capsule, I stay away from it," says a worldly California coed, applying the American-consumer standard that if it costs enough, it must be all right. Whatever the users' criteria or confidence, they are most likely to get such substitutes as the animal tranquilizers, which are known to West Coast aficionados as "hog" and to East Coast fanciers as the "peace pill...
Kicking a Cat. One hopeful but skeptical Manhattan hallucinator recently submitted one of his trusted $5 caps of "THC" to Arthur D. Little Inc. of Cambridge, Mass., for chemical analysis. The disquieting, bad-trip report: it contained less than one-hundredth of one percent of THC (the rest was a common tranquilizer). In that low concentration, one cap would not be enough to give a mouse dreams of kicking...
Marijuana itself is so variable in potency that the National Institute of Mental Health announced last week that it will have five standard strains grown under contract at the University of Mississippi. At the Research Triangle Institute in Durham, N.C., extracts-including THC-will be prepared from this pot, and the N.I.M.H. will let a limited number of qualified medical researchers test the products, under strict control, on human subjects. That way, N.I.M.H. hopes eventually to find out what are the standard, predictable effects of pot and its various derivatives, including genuine THC...
