I just watched a documentary on how America is medicalising its children with amphetamine with phony invented conditions like ADHD, which every child is said to have just because their concentration improves after taking them. Hardly surprising, since amphetamine has always had this effect on everyone who takes it.
University students are all taking it, whether 'diagnosed' and give prescriptions supplies, or buying from friends and the black market. What is driving this is the insane competitive atmosphere in US schools, colleges and businesses, where people are pawns for profit making and efficiency is all.
Amphetamines are addictive, and long term use causes reduction in dopamine and depression.
With the war on drugs [largely cannabis which has a large number of health benefits and medicinal uses] still continuing on behalf of big pharma, they are now addicting the whole population to their products through psychiatrists and doctors with flexible ethics.
