99 Despite originally intending to allege against the applicants a conspiracy to import not less than a commercial quantity of the drug, the Commonwealth agreed to accept a plea from them of guilty to the lesser charge of conspiring to import not less than a trafficable quantity of the drug. Logically, as it seems to me, that agreement results in the need to treat the total conspiracy for all purposes as one to import no more than 499 grams of the drug, all told. On that basis, it seems to me that evidence that, in fact, the intention was to import more than a trafficable quantity of the drug would be irrelevant and, therefore, inadmissible. It is, I think, clear that the intention should be taken to be that a total of 499 grams of ecstasy, that is, the maximum quantity falling within the definition of a trafficable quantity, would be imported and no less than such maximum.
