In Experiment 1, psychostimulant methamphetamine and cannabinoid receptor agonist methanandamide were injected 7 days to two groups of mice either at the doses of 2.5 mg/kg/day or 0,5 mg/kg/day. On the day 8 all mice were given a "challenge dose" of methamphetamine 2.5 mg/kg to check a development of the hypothesised sensitization. In Experiment 2, methamphetamine and combined methamphetamine+selective CB1 receptor antagonist AM 251 treatments were injected 7 days to two groups of mice at the doses of either 2.5 mg/kg/day or 5 mg/kg/day. For the same reason as in Experiment 1 "challenge doses" of methamphetamine 2.5 mg/kg were given to all mice on the day 8. In Experiment 1, it has been shown that compared to control animals this procedure elicited in both methamphetamine and methanandamide pre-treated groups behavioural sensitisation: significant increase in distance run and fast movements and a significant decrease in resting time. Conversely, in Experiment 2, while in the group pre-treated with methamphetamine a significant behavioural sensitization was present the mice pre-treated with the combination of methamphetamine and AM 251 responded with significantly lower metamphetamine behavioural effect when compared to just methamphetamine sensitized animals.
