The Real ID program wasn't targeted at dealing with heroin in communities, so naturally, it won't make a difference as far as that goes. 

Its purpose is to identify those with legal immigration status and state residency versus those who don't. So you must show a passport, original birth certificate, immigration documents, etc. along with proof of where you live to get one. 

Details of what's acceptable are here:  http://www.dol.wa.gov/driverslicense/edlproof.html

Also, with WA's proposed law, nobody has to get an Enhanced License or ID. But if you don't, you'll need a passport or similar to fly domestically (next year) or enter a military base (now).  

I've applied for drivers licenses in several other countries while living there, and this is nothing unusual. Time for the US to catch up.
