true. according to the NIH
The theory that marijuana is a gateway drug is a myth. Propagated by the anti-drug community, which has little or no evidence to support it. There is actually some theories that suggest that alcohol and tobacco are the true gateway drugs. So in no way is marijuana a gateway drug. It ultimately comes down to the will of the person who decides to do drugs, not the drug itself.
It all depends on the person. A gateway drug is a drug that people start using and then begin to use other stronger drugs once the "high" of the initial drug isn't enough.
