I just check some source material and drugs do say +1 IP. So I can see where you are coming from. I don't think they stack personally. It just doesn't make sense to me given the cost in karma/neuyen/essense for getting 4 IP augmentation if you can just have 2 or passes and juice up when you really need it.
I see your point.
Personally, i believe that the fact that all initiative-enhancing drugs in the BBB give you 6S
unresisted damage after they wear off makes up for that.
So, even if the effects of various drugs would stack (and there's no rule saying they don't), a user taking cram, jazz and kamikaze at the same time would be wrecked by 18S unresisted damage afterwards, rendering this 4 cheap IPs for the really desperate.
I tried to deliberately break this by using timed autoinjectors/toxin removing implants in a theoretical build, but all the stuff in
Augmentation either didn't completely filter out the drugs or couldn't be turned off temporarily, i think.
Maybe this is on purpose, maybe i didn't look hard enough and oversaw the ultimate pharmasam build.
