My koala is having the same problem.
He made a vaporizer out of a lightbulb and eyeballed ( still no scale ) doses ( he tried match's head and a pencil eraser size doses ).
Harsh smoke, taste like burning plastic, lightheaded ( had to lye down one time), but nothing besides that.
Actually when he lied down he felt like he was on a bed of waves ( it's hard to explain ). It was a very new and relaxing sensation that lasted less than 1 min.
My koala doesn't know if it was a real effect or just placebo.
He's gonna go and buy a decent little bong or pipe to smoke it, he got tired of wasting unknown doses of the precious powder and failing everytime with the lightbulb.

a lot of people report no success with the lightbulb method. A very big part of the whole deal of dmt is the technique for smoking. SWIM has seen several people that take one or two hits, let the smoke go too soon or start coughing, leave a lot still to be smoked, and then complain they dont feel much. One has to go with full courage, slow and steady big puffs, holding a lot. Also DMT can degrade without vaporizing if the heat is direct, thats why sandwiched between ashes is a good option

30mg for SWIM is not enough anyways, 50mg is a good dose

I've had a ton of success with Noman's TEK, nearly 1% yield, everytime! I'll paste my version of the TEK. Take it with a grain of salt though, this was rewritten for MY mind to understand, which I think everyone should do when they are making DMT because its the best way for you to really understand what you are doing

DISCLAIMER: This Is A Personal TEK, some details were omitted due to general understanding of Nomans TEK.

1.) Fill a Jar with 50g powdered MHRB, 750 ml distilled water and 50g 100% Sodium Hydroxide
2.) Shake the solution for 1 minute and let sit for 1 hour
3.) Warm a water bath to ~110 degrees F (HOT tap water) and set Naphtha in it, let time for heat dispersion to occur, so do this maybe 10 minutes prior to the hour mark of Step 2
4.) Add 50 ml of naphtha to the mixture and swirl and tip end over end for 1 minute, let settle, and repeat 3 more times… Do This Over The Course Of One Hour, Keep Jar Warm in HOT tap water bath.
5.) Separate the two layers, using separation funnel!
6.) Add 5 ml distilled water with a PINCH of sodium carbonate [~8.5 ph] to the naphtha, shake like hell and separate using the separating funnel
7.) Do two more washes with only distilled water… this is to get rid of any leftover lye and give a pure product.
8.) Put top layer in a jar and place in freezer (COLDEST SETTING)
9.) Do Four Pulls. (Repeat 4-8 with warm naphtha of course)
10.) Let the four jars sit in the freezer, with MAX cold setting on, for 24 hours
11.) Now you should have some crystals.
12.) Get a jar, put a funnel in it with a coffee filter, and pour the naphtha through.
13.) Put a lid on that naphtha, use it for next time
14.) Let the crystals dry and do what you want with them

Lightbulbs suck. The smoke is also pretty harsh by using this device. No comparison to "The Machine" ...

leaf bed method.

Did you buy this aladin's lamp or did you make it, because I can't find it on google?
