You should def be able to "milk" a scorp for narcotics

When I was a fresh noob to ark I'd tame 3 scorps. I'd ride one and have the other 2 set to follow and there wasn't anything that could stop us

Scorpions make a great early seafaring mount if you hold the jump key ( space bar by default) a scorpion will float above the water allowing you to get past most Puranas without being attacked, this can be extremely useful for crossing dangerous rivers or even oceans.

If you're trying to work your way up the kibble tree these guys are a fast tame and produce medium eggs perfect for regular kibble so I would recommend to tame using spoiled meat and farm kibble
