District Judge N N Shrimangale found Firoz Shaukat Khan guilty under section 328 of IPC (causing hurt by means of poison) and also imposed a fine of Rs 5000.
Khan was prosecuted under Indian Penal Code as MD powder was not classified under Narcotic Drugs and Psychotropic Substances (NDPS) Act when he was arrested in 2014.
Police had received a complaint that a youth in the area had fallen sick and hospitalised after consuming the stuff sold by Khan who works in construction industry.
The prosecution examined seven witnesses including a physician during the trial.
The court rejected the plea of the defence for leniency on the ground that Khan was the sole bread-winner for his family.
