Heroin has no medicinal use. I was giving an opinion on the fact marijuana does have medicinal properties, that’s all.
Heroin could easily be used in place of morphine if needed. It is also so similar to what is used by veterinarians that you might as well just call it that. And as far as medical uses for marijuana, you can take out everything that gets you high and still get the same benefits. So what’s the only point in smoking it? Not for the medicinal properties.
