Can i legally buy/posses gun? WA state

[zaitz]

to lose your right to carry or possess, you would need to have been convicted of a felony or of a domestic violence or to have been found mentally unstable enough to require some commitment.

It sounds like your felony charge was dismissed and that you pled to a misdemeanor . . . IF that is the case, and IF there is nothing else surprising you have not mentioned, you probably can purchase a gun, but I am not a lawyer and not making you any promises. One other way to "lose" the right to have a gun, temporarily, is to be charged with certain crimes and be before trial or decision . . .

Third the 4473 asked about addiction to "illegal" drugs.

This. The federal government lacks the authority under the 21st amendment to flatly prohibit any drug nationally, they only have the power to criminalize smuggling of drugs into states that do have prohibitory laws. At the moment, the only marijuana that is illegal in Washington is that which is untaxed or that which is smuggled in across state borders.

If the OP wasn't intending to actually receive a gun, it would be a violation for the dealer to run the NICS check:

§ 25.6 Accessing records in the system.
(a) FFLs may initiate a NICS background
check only in connection with a proposed
firearm transfer as required by the Brady Act.

'proposed' provide latitude of intent to initiate a check...
