Hello Thefilmbug,
Welcome to the Nexus. I gotta say, I love your username, being a fan of classic movies myself (sci fi too).
We are getting plenty of new members these days who are quite experienced in life and for various reasons are coming to entheogens for answers or even coming back to them after a long break.
I do think you will like what you find here if you have some time to take a good look around. This place is quite thick with very packed information. A lot of good work and research has gone into making this place what it is today.
Given your apparent lack of entheogenic experience to date, I would recommend starting with something a little less hardcore/intense than DMT. Perhaps growing your own mushrooms, then trying some doses of various ranges would be a good start. . . .
Regardless, I do recommend growing and/or extracting your own with entheogens whenever possible. That way you know the chemist, have plenty to work with and are not participating in drug commerce. It can remove a lot of fears and leave you with the biggie - yourself.
I hope you will chose to become an active member of our community and look forward to seeing your future posts. Again, welcome to the Nexus.
