Wha is the average age you will od from a drug overdose if you do drugs?

Many harmful effects. There is no specific age or time from when someone starts trying drugs until an overdose can happen. Some people overdose and die the first time they try drugs; other people continue for years and may not od but will have many other problems: infections, sickness, losing friends/family/work, shabby appearance, brain damage, etc. Best not to start, or else to quit now before anything awful happens.
