Exactly. Many of the medicine that we label illegal, is from the nature, like cannabis. For that purpose also, we should regulate them, so that people would have better and more controlled access, and not have to figure out healing themselves and caught addicted because they have no legal way to get help.
Reality is there are many people who do not trust the medical companies and their "medicine", and are looking for alternative, natural remedies. Misuse is also a big problem, because when there is no legal source, there is no way to assure what you are getting is good, aside from experimenting and finding people who know their shit on this subject, and it can be difficult to look beyond the stigma of society.
This is very much a problem in countries where cannabis is illegal. People buy too much, use too much, because they have no idea or control when they are going to access more. Been through that process. Nobody is denying cannabis is not addictive, it is, very.
But putting it in the hands of people who know what it does, how it does and in what amounts you should use it, this will help people who have no idea to control their medicinal use better.
Of course there is recreational use, abusive use, but this is also partly because we have no real discussion going on in the public about this. Why? Because it's illegal to discuss even, and can immediately label you as a "drug user".
Same goes for different medicine from the nature also, mushrooms, ayahuasca, iboga and so on. If these were understood, studied and regulated, we would have real medicine to heal people with, not just things created by humans which are produced just to keep people addicted and hooked on the bill of medical cost.
Many medical companies know exactly this, and this why I feel many laws are kept in place to prevent natural use, it's just to protect the immoral practice of selling sickness to people.
Just make everything legal already, and have people who have experience working with these medicines act as healers in the process. This is already happening also, but it is not discussed on a public level, as it is illegal and can cause stigma and fear, but I hope more and more people will do it so we can have a real alternative to the current system again in place.
