...consider this exchange between Assistant Prosecutor Alizadeh and the toxicologist:
Prosecutor: Could you experience the hallucination and/or the psychosis if you had a high enough dose of THC?
Witness: If you got a high enough dose, you could have a psychotic episode into hallucinations, yes.
Prosecutor: Now, in this particular case, when you tested the blood and you got 12 nanograms per milliliter for the delta-9-THC, do you consider that a high dose?
Prosecutor: What conclusions did you make from that?
Witness: Well, you have to put things in perspective. This was a very large individual. I think he was about 300 pounds. So for concentration of 12 nanograms in a large person, that shows it was a large dose. In a small person, say like 100 pounds, to get to 12 nanograms wouldn't take a lot. A single joint could easily do that. But when you talk about a larger body mass, just like drinking alcohol, larger persons can drink more alcohol because they have the receptacle to hold it.
By conflating dose with blood concentration, this exchange implies that 12 nanograms of THC per milliliter will make a large person crazier than a small person, which makes no sense. If smoking a single joint can raise a 100-pound person's THC concentration that high, and if 100-pound people who smoke a joint do not commonly behave the way Wilson claims Brown did, why should we believe marijuana helps explain why Brown is dead?
The prosecutors spent considerable time insinuating that Brown had consumed cannabis in the form of the concentrate known as "wax," even though there does not seem to be any evidence that he did and even though it would not matter if he had. If the issue is Brown's level of intoxication, the amount of material he burned to achieve it is irrelevant. The testimony about wax looks like an attempt to exoticize a familiar drug that people do not usually associate with demonic rage or Hulk-like strength.
Then again, marijuana my be exotic enough as far as the prosecutors are concerned. "You explained that the Delta-9-THC has a psychoanalytic effect?" Alizadeh said at one point. "Psychoactive," the toxicologist corrected her. Later Whirley asked, "Could this amount of THC that was found in the blood be—is it possible that someone [could be] ingesting that amount on a regular basis and not be dead?" The toxicologist explained that "marijuana really isn't lethal."
Unless you smoke it before getting stopped by a cop, I guess.
