I'm sitting here, waiting for my buddy and his gf and waking and baking and I just realized that most drugs are actually kinda boring for me due to the various different trainings I have received during my life experiences. I did 2 1/2 years in the military and spent 13 months in officer training, then later did cave diving training and assistant diving instructor training... during all that, we were taught to combat the -ve effects of drug exposure. while i did not receive the advanced level training, I was taught the basics and taught to recognize what the different effects are. The "simplest" example would be nitrogen narcosis while scuba diving. It may occur at any depth for any diver but for the slightly trained divers, we actually do have dive training with my instructor where we induce nitrogen narcosis underwater (usually about 150feet - 180 feet for me, for my instructor, probably never now, he does 300 feet deep dives) a simple way of testing nitrogen narcosis is from a whip cream can.
