Ditto on what the others have stated here. You probably wont find it, and you might get some strange responses when asking.

In addition to that, a word of caution. If you hunt your local head shops you are likely to be directed toward Salvia as a "DMT like experience", or "a wild & crazy psychedelic", etc. I'm not sure how familiar you are with Salvia, but don't be sweet-talked on it by your local head shop.

I have ZERO opposition to Salvia use personally, but I feel obligated say that it's important for you to understand that it is an extremely powerful entheogen; As powerful as DMT, and typically a LOT less pleasant. I just wanted to throw this out in case you are offered it during your search.

Good luck and go slow my friend. Most people have many years of psychedelic experience under their belts before they venture into the realms of DMT. It's no toy, that's for sure. It can be an incredible teacher and healer however.

Peace,
