Dexedrine and marijuana possible synergism?

[Jiggles]

SWIM is currently floating on air right now and has a few questions regarding his state of mind. He swallowed 10mg of Dexedrine about 2 hours ago to help him power clean and whilst cleaning, found almost an entire gram of good blueberry marijuana he dropped in his car last week. SWIM has posted about his bad experiences with amphetamines and marijuana before, but recently has discovered that this particular strain is not like his usual weed (entirely more euphoric, a little speedy even). So he decided that he would smoke a few hits whilst coming up on his dexies, and WOW. He was pleasantly shocked that this combination was just about the best he has felt in the past many many years of his life. He then smoked a trusty marlboro smooth and rocketed even higher than he cuold believe possible. This even beats the best alcohol experience, hands down (and SWIM LOVES his alcohol ). So the questions SWIM has are these:

Are there any documented synergisms of amphetamines and weed that are not already obvious (aka specific chemical reasons not just the anecdotal "wow i smoked some ice and then some green and it was amazing") ?? SWIM can not find anything and has done much internet/library research.

Also, he was under the impression that blueberry marijuana was mostly indica? Why is this experience so different from all of his other ones? Any SWIY's experiences with this combination that turned out good are very welcome, even if SWIY does not have the chemical knowledge behind it
