Welcome to the nexus, terrasect.

40mg is not a lot, so if you are looking for a break through you might want to try all of it. Personally I wouldn't recommend starting out that way though... it's just that after you've tested the waters, you probably will want the full experience and then you won't have enough to do it. For this reason you should probably start reading up on extraction teks here soon. They are incredibly easy once you've understood the process, and so very rewarding. You will not have to deal with buying it off the streets, which we do not encourage here (so try not to mention it further). You might find you develop a different relationship to it if you extract it yourself too. Though that's more a matter of mind...

You could try splitting it up in 10mg and 30mg for a test dose and a stronger dose. Depending on your physical constitution and your smoking technique 30mg might already be enough for the full experience. It is for me, but I'm small. If you want to boost your experience you could add harmalas (sublingual or oral administration for example), but that would mean either buying them from a vendor (there are one or two that sell already extracted ones online) or extracting them yourself - which again is easy and IMO fun, but it does take time.

Personally I've never believed in the "you don't find it, it finds you" thing. The moment I decided I wanted to try it was the moment I began making it happen by putting an extraction together. It didn't find me... I didn't find it... But I guess it has a kind of romantic and mystical ring to it to think of it that way and given the nature of the experience I can see how it came to be.

What motivates you to try dmt?
