When snorting shit which nostril do you use? iv always heard the left is stronger from the right but thats just a myth that flies around id assume. any scientific answers? haha
The more important question is what hand do you wipe your ass with? Unfortunately neither of these are harm reduction topics appropriate for Other Drugs so this thread is being closed.
edit:
also it might make sense to use both to minimize the possible damage one nostril suffers.
