Food. Specifically, peanut-butter bars.
Depends on the effects wanted, honestly. For relaxation, nothing beats some herbal tea to combine with.
For anything else, it tends to depend on your environment. Being alone with pencil and paper are great for an introspective state, though for me it tends to result in odd artwork.
Only the common ones(soda can, corncob, aluminum foil, etc.)
Not very, I prefer other means of reaching different experiences
12? Not sure, it's easily been more than a decade.
Sitting in a car while someone else drives, windows down. The motion, the feeling of wind on my face, the relaxation… All combine for a perfect experience.
>How hard is it to get in your area?
Probably not too difficult, but I just moved here recently. Everything is easy to get here, though. US Gulf Coast.
Lots, but my favorite has been with friends, at a fair. Spent an hour or so trying to find our ride because we had to cross a corn-field. And ate a ton of deep fried fair food. Was amazing.
Any type of stimulant tends to be fun, depressants tend to knock me out, and combining it with ethanol is a terrible idea for myself.
