This whole thread, like TM's drug use is a moot point UNLESS there is absolute proof that GZ's medication made him go over the edge.
So far, nothing to indicate GZ's meds made him go over the edge.
BBM.. We don't know that...Personally, I'm interested in knowing how long he had been taking adderall, who prescribed the medication to him and was he taking and refilling his prescription for adderall on a regular basis. Those for whom Adderall is properly prescribed are monitored very carefully for the first few weeks.
It's a fact adverse short-term psychological side effects can include paranoia, psychosis, anxiety, and severe depression. Also if a person is taking someone else's Adderall, the dose may not be right for them.
Also people have been known to snort Adderall which puts them at an even higher risk for untoward side effects. The potency and the speed of the onset of Adderall are both greatly increased when it's snorted rather than ingested and digested. The risk of dangerous respiratory problems, cardiac arrhythmias, and paranoid or psychotic reactions are all significantly greater.
Bottom line.... Adderall does have a high propensity for misuse, abuse, and dependency.. JMHO
