Hey you guys, my buddy and I have been working together to make ourselves some e-cigs that have cartridges filled with a tincture of THC and glycerin, and it seems like we have everything we need except weed. Since this is in general a great idea for anyone looking to get stoned and be low key about it, I've made this brief how-to guide. Here's what you'll need: 1 rechargeable e-cig 1 e-cig flavor cartridge 28 fluid ounces of glycerin 1 ounce of weed 1 mason jar 1 grinder 1 paper clip Fill the mason jar with your glycerin. Then grind up your weed and put it in the mason jar. The longer you let this sit, the more THC will be absorbed into the tincture. You will get over 95% of the THC into the glycerin if you let it set for about a week. You can speed up the process by shaking up the mason jar once a day for a few minutes. After you're done, strain out the weed and toss it in the trash. Straighten out your paper clip and stick one end into the hole that the vapor comes out of. Pry the lid of the cartridge off. Inside there should be a small plastic tube with the flavoring and a bit of cotton used to absorb it. Take this out. If you have nicotine in your cartridge, you must be careful to not get any on your skin as it easily absorbs into flesh. Wash out the tube and the cotton and let it dry. When it is finished drying, fill the tube with your tincture and insert the cotton. Do not overfill it, you only want to add about 3-5 drops. Re-assemble your cartridge. Screw the cartridge into the e-cig, and you're finished! Your e-cig is ready to be smoked. The THC e-cig is a virtually foolproof way to be able to get high without anyone knowing that you're actually smoking weed. You could smoke one in front of the police and they wouldn't even think to question you.
