Mixing Methadone and Nitrous Oxide (nos)
Caution
Each makes the other stronger, so you can lose balance or pass out without warning. Take less of each than usual, do not use alone, and keep naloxone nearby.
Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Memory blackouts are likely.
The risk here is to the experience — intensity, panic, thought loops, confusion. Physical harm is unlikely at ordinary doses. Setting, company and dose do most of the work.
