Or can just like get one of these and a drill with a zip tie. Poke thst through a nice solid topped box and cut away.

Man I just thought I can’t imagine doing salvia alone. Then came to the realization you’re basically doing salvia alone every single time. With other halucinagynics you often have shared hallucinations or at least thoughts and experiences with the people you’re partaking with but with salvia the minute you hit it you’re on your own on a very personal journey.
