What is the point of taking half a hit? He'd be lucky to get a decent body high off that. I'm not a hard-head. I tend to encourage low doses and moderation, but I don't see the point is splitting tabs at all.
Most who would say that are those who never encountered really potent acid, it depends per region what the standards are. In most regions they are such that 1 hit should get you a moderate trip, in others you on average need at least several to get anywhere.
I'm not trying to be elitist but as it happens the social circles Ive been in here in The Netherlands keep quite good standards that on average suggest that half is enough for a beginner.
If you never heard about other regions with other standards it's easy to think that it's the same everywhere else. So I'm not saying: half a hit should always be enough, I am only saying that there is a possibility it is if the dose on your batch is a relatively high one. If you assume that the dose is low, you might have a difficult experience if it turns out differently.
And you normally can ask your friends to get an indication of the standards.
