Questions

I've done shrooms and lsd a few times, but this is my girlfriends first time. We are planning on tripping some liquid shrooms this Saturday. Should be equivalent to about 1.75g for her. I'm taking a bit more. Probably around 2.5g. So my question would be how long could I expect her to be 100% unable to respond to a text message from her parents. Or would that not even be an issue. We will be with 2 other close friends who will also be tripping. If we al reviewed a simple text message could we send one that sounded fine.
