I have a white oblong pill and it says watson on 1 side and 385 on the other what kind of pill is this?

This is a highly addictive pain pill. It would be very dangerous for you to consume without proper prescription. Please throw the pill away.

In the future I suggest taking a pill to a pharmacist to tell you what it is.

Try looking it up using this Pill Identification Wizard - Database of Drug Pictures
You also need to take the pill to your local pharmacist in order to have it properly identified and discarded!
