The first 5 years no problem, Hauling it up from Brazil, scarey. After 7 years it cost me my marriage, my business and almost my life. Cocaine is dangerous because the "high" lasts a little while, 30 minutes or so but the effects on the body; blood pressure, heart rate increase, take about 6 hours to wear off. I quit in 1983 when a friend I was partying with had a heart attack in the middle of a weekend binge. Yes we had gone through 7grams or more, but he just dropped in the middle of the floor. Calling the cops sucked, then there was the search. Afterwards I tried to hook back up with my wife and children no luck I had burned that bridge while coking. So if you want to take advice from a grandfather; don't waste your time and money. Ever heard the saying "Cocaine is God's way of saying you have TOO much money" Just my experience; the doctor
