My guess is the doper may have washed-out of seal training due to drug abuse.
Your ire should be directed at HIM for disrespecting the training opportunity he had.
and from my understanding of SEAL training, you're not allowed oodles of time to sit around on your hands and get high...
maybe this kid did in fact get thrown out of SEAL training for smoking reefer, but I doubt it. I think you shouldn't let your blind hatred for a naturally-occuring herb to cloud your otherwise probably OK judgement.
illegality does not constitute criminal behavior. crimes have victims and perps, by definition. rapes, murders, robberies, vandalism, extortion... these all have victims. growing and smoking marijuana has no victim.
SMOKING MARIJUANA IS NOT A CRIME
