Sufferers exhibit a gradual deterioration of the lungs caused by pollution and tobacco smoking. The lung air sacs become distended and rupture. Symptoms include breathlessness and blue lips.

Cannabis is shown to reduce the frequency of attacks.

This is a medical disorder involving episodes of irregular electrical discharge within the brain, characterized by the periodic sudden loss or impairment of consciousness, often accompanied by convulsions. Cannabis is shown to reduce the frequency of attacks and researchers have discovered that three compounds found in medical cannabis can help to reduce and control seizures. CBD was tested on 15 epileptic patients, of whom 8 were given doses of 300mg. The remainder were assigned a placebo and treated for over four months, whilst continuing their past anticonvulsant drugs. Of the eight CBD-treated patients, four remained free of seizures, three showed partial improvements and one showed no response.
