Natural and most synthetic cannabinoids are relatively insoluble in water, but dissolve in fats and fat solvents and are therefore called lipid soluble. /-9-THC produces almost all the characteristic specific pharmalogical effects of crude cannabis mixtures. THC potency has increases since the 1970\'s but has been about the same since the mid-1980\'s. All forms of marijuana are mind-altering. Marijuana is usually smoked as a joint or in a pipe or bong, although recently it has appeared in cigars called blunts.

However, in heavy chronic users, traces can sometimes be detected for weeks after they have stopped using marijuana.

Their is a lot of contraversory over the legalization of marijuana and this debate has become more popular within the last few years. Many people want to leagalize it for everyone and others want to legalize it for medical purposes only.

This was the largest in U.S. history. 87 percent of these were only for the posession of marijuana and were not dealers. Since 1965, there have been over 11 million arrests for it. Right now, there is an estimated 15,668 people in federal prisons, 13,670 in state prisons, and 7,222 in local prisons for the use of marijuana. This is one of the main reasons for the debate of the legalization of marijuana. Their are many pros and cons on this issue and there will always be contraversy on this subject no matter what the outcome is.
