Data presented as mean (SD).

PE1 = phenylephrine dose 1; PE2 = phenylephrine dose 2; IV l -Meth = IV l-methamphetamine

* = significantly greater than 16 inhalations

† = significantly greater than 32 inhalations

‡ = significantly greater than 64 inhalations

§ = significantly greater than PE1

|| = significantly greater than PE2

¶ significantly greater than IV l-methamphetamine

** = significantly greater than baseline
