Tyreke Evans tested positive for "drugs of abuse." According to ESPN (when Chris Andersen was dismissed for this), "The drugs on that list are amphetamine and its analogs, which include methamphetamine; cocaine; LSD; opiates, including heroin, codeine and morphine; and PCP."
It does not mean Evan's took all of them. It simply states which one is considered drug of abuse and harshly judged.
LSD; opiates, including heroin, codeine and morphine; and PCP are not analogs of amphetamines. Amphetamine is a central nervous stimulant. You could throw cocaine on that list as an upper but it's not in the amphetamine family in a strict sense...
You're reading it wrong. The list is:
1. Amphetamine and its analogs (which include methamphetamine)
2. Cocaine
3. LSD
4. Opiates (including heroin, codeine, and morphine)
5. PCP
No one is saying that LSD, etc. are amphetamines
