Hi... Nothing can be said without assessing his condition. These substances impact different brains differently. Combining marijuana with dextromethorphan may create some psychotic symptoms and has potential to bring a relatively persistent change in the neurochemistry of the brain. It will now require a proper psychiatric evaluation and medication to address the imbalance created by this consumption of substances.
Next Steps
