It isn't hard to make hash oil. You just soak the cannabis in your choice of material and evaporate the chemical using low heat or nothing at all.

But saying it isn't dangerous is untrue. Many people have blown themselves up being careless doing it.

One of the main threats is doing it inside with no proper ventilation. What happens is the chemicals fumes start to evaporate and build up in your house. Any spark can blow you to pieces.

Another threat is using an open flame. It's highly flammable stuff.

Another one is some people let the chemical heat up to too high of a temp. and it combusts into a huge flame.

But what it all comes down to is common sense, and some people either weren't born with it, or haven't been taught to use common sense. I mean, before anyone should try this, they should know they are dealing with a highly flammable material, and adding direct fire or extreme heat will result in an explosion.

Not saying it is dangerous is misleading. It is very dangerous if you don't take the proper precautions.

Out of the many times I've made oil, I have never burned myself. The only time it caught fire was when I did it outside on a bunsen burner and I let it sit on the flame for too long. It started boiling big time then blew up.

That was my own fault though.
