the only way to smoke it effectively is to basify it back to the free base and smoke that
yes it's much easier to vaporize as the freebase however the freebase is caustic and damaging to tissue. you can smoke the hcl salt and it's better for you because it's not caustic but you have to really be good at temperature control. mdma hcl has a melting point of anywhere from 107C-159C depending on the hydrate form of the salt. you can take some absolutely pure clear crystal or white powder mdma and heat it to its melting point and it melts to a brown viscous liquid, if you heat it just a little bit more it will begin to vaporize. if you apply to much heat you can decompose the material probably destroying the methylenedioxy group first.
anyway i've smoked mescaline hcl and mdma hcl before. i did it with a flame but it was a very attentive and patient process keeping the flame at the right distance and watching the material slowly melt then move it a little closer to increase the temp and vaporize is, inhale the vapor. if you scorch it then you lose obviously and it's way too easy to scorch it if you use a flame. but i successfully pulled it off for both. with the mescaline i only got a nice buzz and mild hallucinogenic activity, very light effect but far beyond placebo, this is because mescaline hcl requires a large dose. after i inhale it, it smelled/tasted incredibly aromatic which was surprising and i blew out a perfectly white smoke which smelled amazing. it was the type of fragrance you would like to burn around the house, quite pleasing and the taste was very light and similar to the smell. when i smoked mdma i followed the same procedure. as we all know mescaline and mdma are bitter as hell taste-wise but both were very pleasing to smoke as far as smell and the taste was so light it was a non-issue, no bitterness of any kind. mdma hcl's fragrance was very reminiscent of mescaline's but noticeably different, it just had a similar wonderful aroma to it. it smelled like a blend of flowers mixed with something else very pleasing. mdma comes from precursors that are very fragrant. safrole is wonderful, typical root beer scent but if there is a large amount it can get very strong and linger forever practically. isosafrole is similar to safrole but lighter on the nose, it's more pleasing than safrole. mdp2p smells something like flowers and is the nicest smell out of them all. mdma freebase smells fishy perhaps due to excess methylamine (doubtful because excess methylamine freebase gas is liberated upon use of excessive NaOH solution plus i believe it's more soluble in water than toluene/xylene - the mdma freebase's extraction solvent) or perhaps that's just how the amine freebase smells - which i believe is the case. mdma hcl has no smell it's bright white and odorless, until vaporized.
anyway i usually take 300mg mdma hcl orally at once, 100mg no longer does much to me but give me a little buzz, my tolerance is kind of ridiculous i know. anyway i put out 100mg of pure mdma hcl to vaporize. it took several minutes to even smoke half of it so i called it quits, it was just very difficult plus my eyes were beginning to wobble. each route of administration has different effects. orally is the best IMO, apparently tossing it up the rear end has a slightly different profile unique to itself, snorting it is more shallow feeling - you get euphoria and more energetic but the empathy is gone - i don't like snorting it at all because the empathy is my favorite quality. IV'ing it is supposedly more psychedelic, closed eye imagery being pretty intense but i've never IV'ed anything before so this info is 2nd hand. smoking it was incredibly sedating. i usually take 300mg orally to get to where i wanna be, i can drive on 200mg with no problem at all - no safety concerns. so i ended up just smoking 50mg then i went to drive to the gas station to pick up a drink. i thought since i only smoked 50mg i'd be perfectly fine - wrong. it hit me like a ton of bricks as i was driving, it only took a few minutes for it to reach the peak. if you would've seen me you would've thought i was on heroin. i was nodding hard, i didn't feel any stimulation at all except for my eyes were wobbling around uncontrollably. i started to drift out of my lane while driving and turned around immediately and went home, from smoking just 50mg i was in no condition to drive. as soon as i got home i plopped on the bed and zoned out to music with my eyes closed. next thing i knew i was waking up a couple hours later, i have no idea how long i'd been asleep or how long the peak truly lasted but it was very sedating. the trick is to carefully vaporize it and vaporizing the salt takes a lot of time/patience.
