That's what i thought too..

With this attitude, i'm sure you and your friends will have a nice experience.

If you use perhaps a Gramm of dried shrooms per person as a test run you should be safe and feel some effects like maybe closed eye visuals, feeling a bit drunk and or euphoric. you could stack up to maybe 2-3 Gramms a week later for a stronger experience.

I wouldn't recommend taking the meds at all. In case anything goes wrong, one should first concentrate on their breathing and maybe eat some sugar or drink a glass of orange juice or even sing (Terrence talked about it ).

It´s just nice to have a benzodiazepine just in case. But most of the time one doesn't need it. In case of an emergency just use the benzo, not the risp. It seems to be a medium long acting very potent benzodiazepine. So 0.5mg has the effects of 10mg Diazepam, what is quite a bit. Maybe 0.25mg would be safe to use. This would be equal to 5mg Diazepam.
