Our good friend Doctor Sniffles wrote his report above your post.
Soon after writing that post, he noted a climbing pleasant euphoria. The good Doctor then tested more and began to roll along nicely. Concluding that the substance is most likely MDMA.
Doctor Sniffles did further experiments by combining this feeling with various activities, such as playing video games, vaping THC, and laying on his bed with the lights off. All these activities paired very well with this feeling and the Doctor feels quite confident in concluding that this substance is indeed MDMA of some form. Whether it is indeed plain ol' molly or a synthetic analogue is difficult to know without proper equipment, as Doctor Sniffles was banned from the lab for hiding samples in his underwear to take home, so he is now limited to what he has in his home setup.
I feel like the fact it vaped in glassware would lean towards a synthetic of some description, id be interesting to see how it goes in a test kit.
Doesn't MD usually just burn and isn't really known for smokeability, which you touch on in your initial comment also.
Only freebase MDMA actually vaporizes too, so.. Yeah I dunno, seems like it'd be a rare thing to find but I haven't played with a lot of that stuff in a long time.
As someone who got out when RC's came in then got back in once they were accepted I do feel like you seem to find them shits everywhere, especially in random untested gifts.
The rural area where I live had a period where the town was swamped with cheap "molly" that was usually 78% MSM 18% Meth and 4% something totally random that seemed to change the effects somewhat. I used it on two or three different occasions and always immediately regretted the tiny bit I samped as it was always that dirty cheap meth feel with.. something else in it. Some half tweaked prick was out there recrystalizing a whole bunch of things together, I swear.
Or you'd get the caps with 4 rocks of distinct colours/tones/shades/opacity.. Wild shit.
I gave some to methheads I know to try, warning them of the possible adulterants and lack of actually knowing what the fuck it is, one thought it was just really bad meth the other one passed out for six hours after directly ignoring my strong advice of "Don't shoot this up" and it wasn't a quantity that would have dropped that person if it was proper gear.
I'm sure there's been some amazing ones, but the untested nature of RCs always scares me off most of them. Most.
