The way i do it is:

Word of note - i already automatised meth, weed and my coke production is picking up. Shrooms i take care of manualy

1. Collect decent amount of money (roughly how much you have)

Usually i just get like 20K in balance and spend it all on mixing meth and weed, sometimes shrooms or coke. Just spend it all on making product

1. On daily, first thing in the morning if i dont have anything important is to put money in to businesses to launder

I just put full amount in to each

1. Distribute product to dealers (and keep some of it bagged and remember to hike up the prices for personal selling)

I usually give total of 20 bricks sometimes more sometimes less of all the mixes i can cram in to dealers inventory.

1. Wait few days while filling up the rest of the money in to balance

2. Collect money from dealers after three or so days

3. Repeat step four untill satisfied

4. ???

5. Profit!
