Using neurochemical method, evidence was obtained that cannabinoid CB(1) receptors are localized on noradrenergic terminals and their stimulation by WIN-55,212-2 reduces the release of [3H]noradrenaline evoked by axonal activity in a frequency-dependent manner. At stimulation rates of 1 and 3 Hz,
Introduction: The use of cannabis, cocaine or heroin can be responsible for many respiratory complications including asthma.
Objectives: The aim of this systematic literature
The possible role of marijuana (MJ) in inducing sensitization to Aspergillus organisms was studied in 28 MJ smokers by evaluating their clinical status and immune responses to microorganisms isolated from MJ. The spectrum of illnesses included one patient with systemic aspergillosis and seven

Pneumomediastinum may occur during marijuana inhalation but only rarely has pneumorachis (epidural pneumatosis or aerorachia) been reported. The usual mechanisms that produce pneumomediastinum include severe acute asthma, toxic-induced bronchial hyperreactivity, and barotrauma caused by Valsalva's
After experimental induction of acute bronchospasm in 8 subjects with clinically stable bronchial asthma, effects of 500 mg of smoked marijuana (2.0 per cent delta9-tetrahydrocannabinol) on specific airway conductance and thoracic gas volume were compared with those of 500 mg of smoked placebo
