I bought a cheap m3th vaporizer pipe at a ghetto tobacco/pipe shop. They have them at head shops and online too. They're good for Dimitri too, actually what a lot of people used in the old days. They're the most efficient least wasteful way besides a really dialed in vaporizer. It's basically a glass tube with a bulb on the end. The bulb has a hole on top to draw in air.
There's lots of other kinds of glass vaporizer pipes, even bongs, where the flame never directly hits the material. I like the old school simple m3th pipe for it's simplicity and sturdiness. My friend says in high school when they used them for biker craink they called them 'one eyed Jacks'.
You heat the glass on the bottom which causes the material to melt and give off smoke and vapor. It's tricky to use at first but you figure out the right technique quickly. The trick is to roll the bowl carefully to move the substance from hot spots to cooler spots to keep it from burning or cooling too much.
A lighter is perfect, you don't want a torch or something fancy because it'll get too hot. If your glass gets too hot and you're worried the liquid might burn when you set it down, you can carefully set it on it's side. The liquid will run to the side of the pipe and solidify as it cools. Likewise material that's stuck to the side can be reheated to a liquid and will roll to the bottom when you upright it.
Once you get the hang it's a really fun way to smoke. The cheap ones for quackheads are made with thin glass. If possible you want one with fairly thick glass to limit breakage and to not cause the material to heat too fast or get too hot. They will get greasy and nasty after a few uses. Easy to clean with rubbing alcohol and salt, shake and rinse and repeat.
I certainly recommend the approved vendors here because they have a history of safety and consistency. That's why we're sponsors. However there are vendors in Canada (and I believe Holland and China but no experience with them) where this stuff is legit for analytical purposes that operate like regular businesses.
This is one of them. They send the official safety paperwork to cover their asses because the stuff is technically legit here for research as well. Except you'd probably face harassment. I'm guessing problems with harassment is why the other ones require much more stringent ID checks. One way to tell the scammers from the legit is that the scammers serve stuff that's on the naughty list here. Legits have a long list of states and items they won't serve.
I've been scammed once, decided I didn't like it and do a ton of research about what I choose. Health and safety are critically important as well. Not sure why I'm going through all this trouble to shill for these guys. I didn't even ask you to say I recommended them so I could get a discount. They already sent me coupons so it didn't matter anyway.
They aren't my heroes or anything but they did me right which I appreciate. It's also important to note that there have been approved seemingly legit vendors here who have pulled exit scams. I've always been about impressions, vibes, and research, the one time I got careless I got ripped. If someone you like is acting shady or non-communative there's no harm in waiting a few days to see if something's up. There also seem to be shit-stirrers here that like slamming a vendor when they make a mistake. Got to differentiate between that and real danger signs.
