I want a drug that's like marijuana but is 1) substantially less potent and 2) doesn't impair memory. The reason for this is that I've noticed that while under the influence of small amounts of marijuana, the "connection-making" circuit in my brain is far more active. Of course, if it's too active then this is an impairment (everything becomes "connected"). But I'd rather have to reject spurious connections than to not have access to potentially insightful connections in the first place.
