Famous question- is marijuana a gateway drug? in Substance Abuse / Addictive Behavior - 8-balls, Highballs, Deal Me in One Last Time Posted May 16, 2013 It most definitely depends on the person. For many, marijuana is all they need. But then there are others, like myself, that have a tendency to explore other intoxicants after being introduced to it. If I've learned anything about marijuana through my use it is that it's an extremely versatile drug. In addition, it's going to amplify what's already going on in your brain. So it certainly serves as a gateway drug for a lot of people but it's not a cookie cutter situation as the media makes it out to be. Of course, this is only my opinion based on my own drug experiences and watching the experiences of others around me.
