Drug use of any kind wreaks havoc on your body and your brain in many ways. In relation to COVID-19, people who abuse drugs are at risk for serious complications as drugs negatively impact your lungs and the arteries in which blood flows to your lungs.
Opioids slow down the breathing. If you already have a respiratory disease like asthma or COPD, you have increased risk to die sooner than if you were not taking opioids. Even if you do not currently have a respiratory disease, if you are taking opioids and get COVID-19, your lung capacity will be further diminished from the virus. This may result in severe COVID-19 complications and possibly death.
Methamphetamines cause significant pulmonary damage to the arteries that carry blood to your lungs, as the components of methamphetamines bind heavily to pulmonary tissue. With a positive COVID-19 infection, the risk of negative outcomes is multiplied.
