Hep, whats upbro!
You can get drug tested just applying for an electrician job...... in most cases it's a three year apprentice before you get your journeyman, you can here tested anytime during that time. Once you have your license it all depends on where you work. Going off to start your own thing is a ruff road to take sometimes, where I live alot of them are going MM friendly and doing grow room setups on the side.It's a good paying trade and skill to have. Good luck buddy!!
I had the choice and chose masonry...... alwaysmade great money, ......but the electrician has the better job, more inside work, more sitting in A C truck, and less injuries!
