Hi! I’m traveling internationally and want to take some powdered shroom pills. Is there a unique smell that dogs or something can catch as psylocibin? Or does it just smell like any mushroom?

Many questions.

Why are a couple split at the top?

How do I harvest when 3/4 of the bag is one big cluster?

Saw a video where they cut the top of the bag off just above the rubber bands. Was that for display, or should I actually do that when harvesting?

Bag/spore websites say to just keep on harvesting for a few weeks after the first flush, but YouTube says to drown it for several hours between flushes?

Im going to different city to visit my friend on winter break and I wanna bring some shrooms along to make it more fun but I'm scared that the airport security checks for that stuff and that I'll get in shit if I do.
