Can u and if u can, how do you make hash oil out of marijuana leaves?

Gather leaves.
Take a shit ton of ISO alcochol.
Submerge leaves in alcohol.
Seperate.
Dry.
Smoke.

Or osme other ways with screens n stuff

 

Buy a pound of trim for next to nothing and you'll have all the hash you'd want.

 

Multiple ways

You can take a ton of leaves, give them an ice cold water bath packed with ice and repeatedly filter them through bubble bags untill you've got the hash you want. The smaller micron measure of the bags the more high quality the hash will be

You can also get a tube, stuff it with leaves and run butane through it untill you get oil, at which point you heat it to dissolve off oil and you're left with hash oil which you can turn into budder if you wish

 

yea, for a guide on what to do, look for hashmoufs guide on making all types of hash, it isnt called that specifically, but a search for hashmouf will produce the thread. Qwiso, Cold water, you could get a kief box and kief them, if they are sugar leaves.....
