Now that drugs are really good and cool for martial players in quests/combat scenarios, it would be nice to get new drugs that are also good for casters. Things like increasing caster level for long durations, increasing DC, and/or restoring spell slots are all good ideas for this. Would give a reason for casters to use drugs in the middle of a quest/combat scenario since currently there really isn't much of a reason.
