Does marijuana lead to use of other drugs?

It isn't associated with other drugs. People use marijuana independently of other drugs (such as someone who smokes weed for therapeutic reasons, but refrains from using alcohol or cocaine). If you are inquiring about the 'gateway drug theory', then the simple answer is that people who are open to the idea of marijuana are also open to the idea of all drugs de facto. This is not to say that all marijuana users will go onto 'harder' drugs, I am simply stating that whatever has lead you to marijuana can likely lead you to cocaine (for example) in the same manner. It just so happens that the availability and acceptance of marijuana is high, so it is most likely the first drug one might encounter.

Hope this helps.

<-Excuse me but what are you talking about? the only drug i have ever used have been hash, but i have NEVER been "open too the idea" of other drugs at all. I have been smoking it allmost every day fore five years and never have i been introduced to other drugs simply becurse i don't care for them, the people who gets into harder drugs may start out with hash, but the reason they start taking hard drugs is becurse that they are just plain stupid.. Ps: I recently qwit smoking hash at all (from one day to the other) becurse i desited too take a year without, so that i can travel around a bit. :)
