Yet, most other reports say there is no link between cannabis and cancer. For example, the Kaiser Permenente Insurance study of 1997 that used not a mere 4 individuals but 65000 said there was no link. There is also the UCLA study of 1996 that came to a similar conclusion. Cannabis must be dangerous, it contains 400 chemicals. This is no reason to ban it after all coffee contains 2000 compounds 200 of which are carcinogenic.
Cannabis leads to hard drugs.
However when the same dealer sells them, which they are doing with the present system there is a connection. The Dutch with their coffee shops have removed that link and now the heroin user in Holland has an average age of 44, compared to the UKs average age of 19. This indicates that the prohibition laws are the real gateway. Usually though, the first drug tried by a junkie is alcohol more often than it is cannabis. Cannabis is a lot stronger than it was.
