Chill Dude, for a long time i had an all day habit of cannabis and i don't consider i had a high tolerance and i definitly got wasted every time i vaped.
With combustion it was different but i also mixed with tobacco so it was two main psychoactive and addictive compounds, not just one.
But with vaporizing, when i used to vape all day every day i never exceded 0,4g/day which was my maximum daily usage since i vape.
To me the difference between a recreational and a medical user is much more difficult to assert than it seems at first.
First of all, dosage. And second, frequency. Third, motivation to do it.
These two items change greatly depending on the kind of condition you are treating. Some medical users don't need a psychotropic dose, others do.
This determines right from the start if you have the potential to
Some recreational users vape everyday until they have a minor buzz and others slam their receptors until they have bloodshot eyes.
I don't believe it is healthy to be an all-day user, and it is less healthy the more quantity you use at a time (of course each organism is different and some people have a higher resistance to the bad side effects of chronic use), and the more frequently you do it.
If you have to use it every day, all day for medical reasons you should eat foods and/or supplements that compensate for the usage.
Meditation and exercise should be part of the treatment as well.
