According to the experienced coach, a lot of footballers who were tipped for greatness by pundits could not achieve their goals due to bad influences from friends that ended in drug addiction.
"There are many professional players who were tipped to be very successful with their careers but along the line, they veered off," Amissah said.
"They could not go far because of drug abuse as well as other immoral activities they found themselves in. When you take drugs with the idea that it will enhance your performance in games, you're rather ending your career prematurely but you may not know.
"I'll entreat young players to learn from the sad ending of some of the players who are struggling to cope with life today in order not to make similar mistakes in future. They must be obedient and submissive to instructions from their coaches and also consider their diets since that will help them," he added
Amissah, who is currently without a club, guided Elmina Sharks to the Ghana Premier League for the first time in 2017.
