Cionidine. Clonidine dampens sympathetic activity originating at the locus coeruleus by stimulation of presynaptic a2-adrenergic receptors in the sympathetic chain (Covey and Classman 1991 Hughes 1994). It appears to have some efficacy for alcohol and opioid withdrawal and thus was evaluated for treatment of nicotine withdrawal as well (Covey and Classman 1991 Hughes 1994). Several clinical trials used oral or transdermal clonidine in doses of 0.1—0.4 mg/day for 2—6 weeks with or without behavior therapy. Three meta-analytic reviews reported that clonidine improved quit rates (Covey and Classman 1991 Courlay and Benowitz 1995 Law and Tang 1995).

The extreme events which have been discussed differ in their characteristic spatial scales of importance. Each event which causes wind-throw occurs on a smaller spatial scale than a pollution event, as recently seen by the very extensive scale of the Chernobyl fallout (Johnston, 1987). At an even greater scale, the projected extent of the nuclear winter will be global (Covey, 1987). Examples of this hierarchy of scales of events are shown in Table 1.
