I have never had any luck with any of that stuff. I've tried various 'sampler packs' from ads in High Times back in the day and the most I got out of it was some free papers or a cool pipe. The stuff they sold did nadda for me. Maybe it's a tolerance level thing. But usually when I tried it, I hadn't been smokin for months and was having hard times trying to connect. Shit, may try it again soon if things don't start working out and depending on what others say in this thread.

Overall, I'd just say buy a small amount so you're not blowing money on crap and don't expect much. YMMW.
