Northern Cali/bay area M30s Fent Warning

From another user:

Hey y’all. Poster about 50 days ago about this but it’s worse now, fake blues got less fake and more potent. Just wanna send out a warning for y’all in the region. Half a fake blue made my friend overdose. It would be safer to not buy any oxy from anyone you don’t know has a script. Grandma’s only. Stay safe guys.
