The effects of ketamine are considered dose dependent. That is, lower doses of the drug produce varying results when compared to higher doses. A dose of 1.0 to 2.0 mg per kilogram of body weight produces an intense experience lasting about one hour.6 One of the most dangerous effects of ketamine is the helpless and/or confused state the user may be put into after use of the drug.
