Very Educative : Routes of drug entry | Processing the Environment | MCAT | Khan Academy


  • Smoking and snorting have two different mechanisms of entry ..also inhalation is fastest for most substances versus injection. This video and lecturer needs to be fact checked.

  • I think smoking and snorting shouldn't be included in the same category as they have very different mechanisms and thus very different effects. You should differentiate between insuflation and smoking. It most certainly does not take 10 seconds for an insufflated drug to reach the brain. Where smoking a drug causes a very fast onset.
