No. It makes you trip out...but it only lasts for like 15 minutes. The higher the extract, the more intense the visuals become. It's crazy. Make sure you have a sitter with you when you try it.
I wouldn't reccomend the joints, because Salvia vaporizes at rather high temperatures, so use a torch lighter, and you'll trip harder. Another let down about it is that one bowl is enough for one person, it gets cashed after one hit. So, sharing bowls isn't an option. But 30 seconds later, you're tripping so hard you won't care.
