Are you sure you're taking the biggest hit you can, and holding it for atleast 30 seconds? I found that a regular BIC lighter actually brought the best trips, and not a torch lighter.

Salvia is kind of hit or miss, but once you break through it's great.

Apparently it has a reverse tolerance issue, so the more you smoke it, the better the tirp will be.

Don't give up, Salvia is a great experience once you break through.

Good luck.
