Hello my friends. I plan to try cactus tea soon. But I don't know what dose to take. What dose could I take to get a strong effect, but not too strong to function normally if necessary? Thanks.

You should not trip unless you're relatively certain that you don't have to function normally. It seems counterintuitive to say you want a strong effect but to still be able to function normally.

Setting is just as important as dose!

Impossible to answer your question with any accuracy
cacti could be anywhere from 0-5 percent alks by dry weight

Start small and adjust accordingly. Maybe 6" on your first try.

I second what adjhart said. If your going to trip you should be ready for whatever happens. If you read endlessness's trip report "impossible is possible" you will see that sometimes you never know what your in for.

If you go into a trip with the thought that you might need to perform some important task you are setting yourself up for possible failure. Best to have time set aside with no responsibilities required.
