This raised....[ prolactin levels]... can be found in blood work and is supposed to be caused by a [non cancerous]... brain lesion...

I wonder if heavy long years of dmt smoking could be conected to [raised prolactin levels?]

At least it is non cancerous... but still a little worry some!

has anyone else found this in their blood work?

you can influence prolactin levels very easily:

just have an orgasm with your partner. the long-term resulting effect is called the coolidge effect.
also gives some insight into long-term relationship dynamics.

I think Mucuna/L-Dopa supplementation is said to reduce prolactin levels.
