Only if you believe that life altering moments must be rooted in a permanent change in your brain. Plenty of people have "life altering moments" without drugs. Its just interesting that a select few chemicals cause most people to believe they have had such a moment. It also seems to be backed up by actual significant behaviour change, which is rare in most social studies. This doesn't mean in any way that these changes are permanent. Nor does the effectiveness of the drug prove that it must be linked to some permanent change in the brain. Not in the same way malnutrition in children does. or b12 deficiency.
