Several of your friends have considered doing drugs, though you have warned against this. lately, one of your friends has experienced memory loss and asthma-like symptoms. what might your friend be doing?
The answer to this would be SMOKING. Knowing that the body has been dependent on the intake of nicotine, the possible side effect to this once it is being stopped is asthma-like symptoms. This is why smokers would tend to smoke and smoke again because of the symptoms when it is stopped. Hope this helps.
