As a supervisor in manufacturing plants I have seen far too many dope heads that couldn’t stop smoking dope even when they were going to be fired.
I have a step-grandson that was smart and normal until he got hooked on smoking dope. Now he is a worthless loser that can’t get out of bed to go to school or work. Now he’ll never be worth a pinch of $hit.
You raise a valid point.
I currently have a person; loves his weed,(but is a binge drinker) worked in manufacturing 15 years ($33/hour), the company changed hands last year & drug screens were announced & scheduled 90 days in advance, and yet he would not stop toking for roughly 21 days prior to being tested. But— if you try to fire people for drug use, they can demand 21 days of inpatient. Instead, they just targeted his butt for a few months, he was tardy 3x’s and then they fired him for cause. (Now he’s on Medicaid and in a 12-step program.)
On the flip side of that equation; Big regional food-retailer here,(union shop) gave up on PRE-employment drug screens, cuz’ they couldn’t get enough applicants to fill the positions. (THC and opiates were most common)
They went to POST-ACCIDENT drug-screening regime. They don’t care what your hobby’s are, but if you have an accident at work, you get blood and hair-screened instantly. If you’re positive, you go into rehab or you resign voluntarily that day.)
I had a neighbor in his 20’s who apparently had a violent nature at one time.....Medical marijuana has calmed him sufficient that he functions normally daily, holds a job etc. He said that other psychotic drugs he had taken did further harm with the side affects ..he still couldn't hold a job nor function normally. It appears Medical marijuana works better for some...and each case is different.
