In closing, Juan said the effects where similar to someone taking a certain prescription, starts with an "A", can't remember what it was called but similar to Ritalin) but 16 hours after the fact, DR would have been tired, maybe agitated, mostly "bark but no bite". It would actually be easy to get a person to respond verbally to suggestions or commands because at that point, they just want to chill out and sleep. DR had already reached his peak high within the first 2 hours, +/-. To maintain that high, he would have had to be smoking or snorting meth every 4 hours after the initial use.
