It could be that the anti-drug movie is one of the hardest to pull off. Even with great setups and decent performances, they can come off as bathos-drenched soap-opera hell ("The Boost" always comes to mind, and it doesn't help when the lead actor acts like he's on crack when he's sober).
"Cocaine: One Man's Addiction," while possibly having one of the most ridiculous titles in TV-Movie history, actually works due to the ordinariness and realism of the characters and plots. There isn't anything here that's going to shock or amaze you: just an ordinary guy sending himself down the toilet and wondering how he got there. But it gets to you, simply because it's so low-key. Dick Van Dyke did something similar with "The Morning After," but it never seemed as life-threatening or desperate as it does here.
Weaver portrays an aging real estate agent who's finding himself edged out of the company he helped build. While he gives his usual competent performance, the real sparks fly from some of the supporting actors, notably Jeffrey Tambor, as a friend of Weaver's whose binge with coke nearly drove him to suicide, and a teenage James Spader, who brings an easy realism (and pain) to the role of Weaver's disaffected son.
With Pamela Bellwood, nicely playing a poignantly injured casual user who initially lures Weaver toward his doom and a mis-cast Karen Grassle, who looks simply uncomfortable throughout.
