You wouldn’t be around other drugs if you can just buy it off the shelf, like you can for alcohol and liquor.
Besides - whatever happened to government staying out of our personal lives? Should alcohol be banned again (prohibition)?
It's a gateway drug. Not for all but for many. If you are around pot you are eventually exposed to and may try something harder.
I know there are folks that don't believe this (usually pot smokers) but they are 100% wrong.
I have seen the evidence with my own eyes and have talked to others that know this to be true also from personal experience.
Don't give me the old alcohol argument either.
