Would it be cool if you take DMT and heroin together,I think the trip might be super bliss and enlightening ,with minimal chance of dark encounters.

Wouldn't it be cool if you stopped trolling?

So far it is pretty wideley understood that most anything taken with DMT (aside from MAOI) just dulls the experience.

Also, I hope you are not a heroin user, and if you are please find the strength to quit.

Ah, bringing me back to the old days... I tried this combo plenty of times when I was opiate-dependent. I agree with anrchy. It detracts from the experience significantly, and as a person who has experienced heroin addiction I cannot recommend heroin use to anyone, under any circumstances.
