 72. Serum Deltas9 THC levels failed to correlate with

 ....... 73° This orthostatic hypotensive response may be more
 likely in patients with essential hypertension and glaucoma.
 In all subjects, this response is abated within ten to fifteen
 minutes by assuming a reclining position°
 74. Determining what drugs are appropriate within the
 context of medical therapy is a constant balancing of benefits
 and risks. All of the drugs employed in glaucoma control
 therapies have serious adverse effects.
 75. In a recent review of Timolol's use over the past
 eight years in glaucoma therapy_ a recent journal article noted
 i that thirty-two deaths have been attributed to Timolol's use in
