The number of people getting hospitalized due to amphetamine use is skyrocketing in the U.S. But, the resurgence of the drug has been overshadowed by nation’s intense focus on opioids.

According to a recent study in the Journal of the American Medical Association, Amphetamine-related hospitalizations jumped by about 245% from 2008. That is far more that the rise in hospitalizations from other drugs, such as opioids, which were up by about 46%.

Amphetamine are stimulant drugs, which are legally prescribed to treat attention deficit hyperactivity disorder and produced ille gally into methamphetamine.

As opioids become harder to get, police said, more people opted for meth, which is inexpensive and easily available.

Doctors have witnessed the drug’s comeback in emergency departments, where patients arrive agitated, aggressive and paranoid. Paramedics and police officers see it on streets where suspects’ heart rates are so high, that they need to be taken to the hospital for medical clearance before being booked into jail.

Medical examiners observe it in the morgue, in few states like Texas and Colorado, where overdoses from meth surpassed those from opioid heroine.
