^^ I always put my chemicals directly in my mouth... it's just a flavor, it won't hurt you. Some of them don't taste bad. I mean, they don't taste good (far from it) but it's not like they induce instant nausea, at least for me. Putting them directly in my mouth produces a faster and smoother come-up and gives me the feeling of being more intimately familiar with the chemical... whether it's placebo or not, it works for me.
Then again, tastes don't bother me. Except for 4-HO-DiPT... NEVER put that directly in your mouth.
