I inhaled properly the first time, and didn't get high. I felt a little different, and by all accounts, was acting pretty messed up.

I think it's more of a mental thing for some people-- they don't know what to expect from the drug, so they don't really notice that they're altered significantly. It was like that with me for every drug I've taken (weed, alcohol, oxy).

The best option? Get a good bong and some dank KB. It's impossible to NOT inhale a bong rip, so it's a good option, and with the dank buds, there's no way your newbie friend won't notice the drug's effect.
