No offense taken just sharing my experience. If people did what they were suppose the body would heal itself and there would be no need for drugs, especially for extended periods of times. Most potheads I know, even the Whole Foods and Acai Berry lovers smoke to relieve stress and use it as escapism smoking at least a gram or 2 daily....not for chronic illnesses.
I am healthy according to my lab results and more importantly and am cognizant, no history mental illness and dependency. Most in my family live to be near centenarian and they are substance free. Noticed the ones who drink or used other substance died earlier or lived a poorer quality of life; they were not as mentally/financially astute as the others. Just my preference. A balanced diet, exercise and surrounding yourself in positive environment does wonders as you pointed out the body can naturally heal itself.
Women (and brehs when picking mates) should be mindful of what they taken into their bodies since a female houses all if not most of her eggs at birth, so essentially what mother does before and when conceiving can potentially jeopardize her unborn daughter's developing and unprotected eggs (grandchildren). Also, behavior patterns follows families.
But let the stoners have fun with their "insomnia". I lived in Germany for some time and just hope the citizenry doesn't morph into vapid stoners like California.
The thing about mental illness though, is that you can't test for it, a lot of times it just happens. You literally snap, so those people smoking to relieve stress are actually doing the right thing. As far as people who don't puff, they still have vices, and I've found they tend to have freaky sex, or shop a lot, or are religious. All of those bring more problems then they solve, so I can't do it, I'd rather just puff. My grandmother is almost 100, and I love her, but she is not someone I like to be around a lot. I find this with a lot of "sober" people. It's like because they are sober all the time, they have to put on an image, but the image tends to be fake.
On the people who did use substances, I agree, but like I always say, it isn't the substances, its how they used them. Chances are they used those things as party items, and the party lifestyle is what brought all the problems, not necessarily the herb or the alcohol.
I agree on the women, and eggs thing, but we know now the eggs can be rebuilt, they are not forever damaged. Again, unless you are smoking blunts, and drinking, while not eating properly, you are not hurting your body. In fact because you are experiencing a high release of neurotransmitters consistently like dopamine, you will enjoy life more, and it will effect other things in your life. I know for me when I puff, less things bother me, and i focus on enjoyment, and being creative, as herb helps you see things differently then you normally would. I notice people like arguing, and just dumb shyt, when they are sober, but they don't see it as them doing dumb shyt. Even me, but its just different when I puff or when I've had long sessions, and still in that relaxed mode. I also have seen some fukked up shyt, and herb helps me think about the shyt without being overly emotional about it.
I know for me, herb saved my life! I had issues that I thought wasn't bothering me, but once I started puffing, i noticed a lot things that was going on around me, and realized I wanted better. Alcohol just made things worse, and I wasn't fukking with the other man made shyt. I tried the talking, and the religious shyt, but they didn't hit me deep like herb did. Then it helped with health stuff that I didn't realize was an issue, until I started studying the body. I doubt I would ever take herb out of my life, especially now that I know how to use it properly, without any ill effects. The positives are just too great to let it go. Alcohol, yeah, but not herb! If I can find older people who live a life I find enjoyable, and they are cool people, I might think about ditching herb, but I have yet to see it. I just see people who have accepted their lifestyles, but they aren't truly happy, that's why they are always complaining about the younger generations, its hard for their brains to change, and adapt to new things!
