Abstract: | - 1.1. The behavioural effects of hashish extract (10 mgΔ9-THC/kg) were compared to those of morphine (20 mg/kg), diazepam (10 mg/kg), imipramine (10 mg/kg), amphetamine (10 mg/kg) and chlorpromazine (10 mg/kg) by testing male mice in a resident-intruder situation.
- 2.2. The drugs were given either to the resident or to the intruder male.
- 3.3. Hashish extract similar to diazepam and chlorpromazine reduced social activities in resident and intruder males.
- 4.4. Intruder males treated with hashish or diazepam were more frequently attacked and submission and flight was increased.
- 5.5. Amphetamine and morphine stimulated locomotion and non-social activities but impaired social behaviour especially in residents.
- 6.6. Imipramine increased aggressive behaviour in resident and intruder males.
