I was experimenting with vaporizing things in a test tube and came across this thread.
Smoking caffeine is great but only lasts a couple minutes.
I tried piracetam after reading the first page of the thread. No effect. But piracetam hasn't ever done anything noticeable for me.
Then I tried pramiracetam. Whoa. That worked. It reminded me a lot of the caffeine. But different somehow. I feel slightly detached from reality on the pramiracetam if that makes any sense. It's not as crisp and clear an effect as the caffeine. But I'm quite bug-eyed and alert on it.
It also seems to be lasting longer than the caffeine.
And, no, I haven't really taken much thought to the safety of what I'm doing.
