is it actually crystals or just powder?
Just eyeball it if you don't have a scale...
If you have never worked with molly powder/crsystal and want a good estimation method...
Go and buy yourself a pack or parliaments. Crush it up and fill the reccessed filter with the powder. Fill it so that its a little over filled. This is generally around 100mg. But powder consistency varies a lot from batch to batch, some is dense and others are rediculously fluffy....
1 batch i had, a tenth was about 3/4 of a 0 sized gel cap. Other batches were about 1/4 of a 0 sized gel cap.
If you just want to eat some rocks of molly... [ ] about the size between the brackets is going to be close enough to a tenth....
You could also do liquid measurment if your eating this with friends.... fill a shot glas with water and pour into larger cup. Do this for however many doses you want to divide it into, for simplicity lets say 10. So you have 10 shot glass amounts of water in a cup. throw the gram into it. 1 shot glass sized amount = 100mg.
if you were to do it with 5 shots you would have 200mg per....
You can work with much smaller amounts of water, im just using this as a simplified method of doing it. 100mg will disolve into a ml or two.
Liquid measurment is the most accurate way of doing this without a scale.
