The reports of Britney Spears’ downward spiral just keep on coming.

In addition to the illegal substances, the pop wreck is said to be abusing prescription medication in a desperate attempt to slim down.

The singer has recently been photographed in public while sucking on inhalers, despite the fact that “she doesn’t have asthma,” a source tells US weekly.
 
According to the mag, Britney is using the chemical epinephrine - found in asthma medications - as an appetite suppressant.

Epinephrine abuse can cause serious side effects including headaches, dizziness, nausea, sleepiness and heart arrhythmia.

Last week an L.A. judge branded Britney a “habitual, frequent and continuous” user of drugs.
