i need to know the maximum time when some1 is charged with manufacturing a controlled substance?

Answer 1

Death penalty is the world penalty that someone could get for manufacturing of controlled substances depending on the volume of drugs found.

Answer 2

If you're asking about the U.S., it depends on whether you're charged by the feds or the state, and if the state, then which state. The penalties also vary according to the drug itself, the quantity, and whether the offender has a prior record. Worst case scenario: life imprisonment.
