I'd like to apologize to how I presented my response to you in this thread. I'd like to explain myself a bit - the issue struck home with me, and instead of going after the issue I put a personal spin on it.
I don't think substances have the ability to ruin people's lives, much as I don't think guns are nearly as dangerous as the people using them;
I'm unsure of your personal experience with substances or people who have abused them, but I know from my own experience that any time I did something destructive, it was my own mind, and my own chain of "logic" rationalizing what I was about to do. And I'd hate myself for it later. But I wasn't in trouble with cannabis - it was an artificial substitute for it that's just about as addictive as heroine and pretty dangerous, sometimes lethal.
Any time a person falls into a habit like that, they're trying to compensate for personal issues they haven't resolved in their own life, and that spiral is what kills them, or leaves them destitute - the substance is merely a vehicle.
Right now, I'm a person who has constant pain and fatigue, and I have trouble digesting food - I'd qualify for medical cannabis if I lived in the right state. Though I don't think cannabis is so harmful that it should only be relegated to medical use in extreme cases, especially when compared to the things that are already legal like alcohol and tobacco, or the things that are de-facto legal like what can be found in gas stations or novelty shops.
Again, I apologize for my rudeness, and I would hope I didn't damage what opinion you may have had for me too much. I'd also like to have this conversation civilly, if you trust me to do so.
The biggest problem for people using newer cannabis is that it does keep getting stronger - the same penalties apply to low grade as high grade, so breeding for street sale concentrates on a single active compound - the compound cited most for transient psychosis and awakening schizophrenic illness. But there's proof
that a certain compound, cannabidiol, is an antipsychotic and a THC agonist, meaning it reduces the psychedelic effects of THC and can actually reduce anxiety, lowering effects on heart rate and blood pressure.
As far as breathing issues - it doesn't need to be inhaled. Honestly, any smoke put into a person's lungs is bad for them.Cognitive side effects
are shown to subside when use has stopped, unless use is chronic (read; near-constant and ceaseless) - which I'm assuming is a constant fog of apathy.
The other points, like not smoking during pregnancy (a fetus shouldn't be exposed to intoxicating plants, that's common sense) and causing cancer
? Well, I obviously have a link for cancer. Also, cannabinoids were recently patented in the US, citing their use as anti-cancerous agents. They work on most forms, and can even reduce a risk of lung cancer.
