On the topic of biases, I wonder why you consider theirs to be "dangerous".
Regardless, their biases to seem to stem from a certain personal experience with marijuana, particularly their friends' habits with it. It's possible this person's "friends who spend majority of their day high" have a substance abuse problem even if not everybody who uses the substance abuses it.
> Because THC is shown to be an effective care for many mental and physical problems. THC itself can be dangerous or even very dangerous (psychosis risk etc) but this doesn't warrant being so overly cautious that we miss the forest for the trees. Facts show THC can be a very effective palliative tool, and it's unclear how much damage you can do with short-term regular use.
To add, it also leads to apologism of (or apathy for) locking people up for consuming THC.
> while biologically correct gave these type of people a get out of jail free card.
Yikes.
I think part of the problem is ever since legalization weed became more mainstream (potentially dangerous) but weed-conservatism (i.e. exaggerating real risks of THC) also became much more common to encounter (also potentially dangerous). The reality is somewhere in between. I do not use THC, but as someone who used it previously and it tremendously helped me, my current mental model and set of anecdotes say you're likely wrong.
