  • ¶ 9. Watts, who owned a wrecker service and auto repair shop, testified as to why he was in possession of the various items generally associated with manufacturing methamphetamine. He testified that his two diesel wreckers were being repaired and that the mechanic performing the work informed him that he needed two cans of starter fluid to assist in starting the trucks. This story was corroborated by the testimony of the mechanic who performed the repairs. Watts testified that he was going to use the aquarium tubing and pump as a syphon hose, which was something that he regularly used in his line of business. Watts also testified that he noticed that Wal-Mart had the two gas cans on sale as a bundle package. According to Watts, part of his wrecker services encompassed taking gas to people who had run out of gas; therefore, he was always looking for a deal on gas cans because he could always use more. Watts further testified that he bought two packs of the antihistabs for his “sinus and allergies” without realizing that he already had two packs in his wrecker. Finally, Watts testified that the reason that he went to both Wal-Marts was that one store did not have a particular item that he needed, and he thought that maybe the other store may have had the item.

    ¶ 7. Archie Nichols, a forensic scientist employed by the Mississippi Crime Laboratory, testified concerning the chemical analysis that he performed on the two cans of starting fluid and four boxes (exactly 192 tablets) tendered to him by the Lamar County Sheriff's Department for analysis. Nichols testified that the cans of starter fluid contained ether, which is one of the components used in the manufacturing of methamphetamine. Nichols also testified that the four boxes of antihistabs contained the active ingredient pseudoephedrine, which is the main ingredient in methamphetamine. Nichols explained to the jury how salt is used in the cooking process. He also explained that the aquarium pump and tubing, which were found in Watts's possession, are commonly used in manufacturing methamphetamine. Finally, Nichols testified that he was not sure how the two newly purchased gas cans might have been used but that they could have been used to either store solvents or transfer the product from one container to another.

  • When you are exposed to an allergen -- for example ragweed -- it triggers your immune system. People with allergies demonstrate an exaggerated immune response. Immune system cells known as "mast cells" release a substance called , which attaches to receptors in vessels, causing them to enlarge. Histamine also binds to other receptors causing redness, swelling, , and changes in secretions. By blocking histamine and keeping it from binding to receptors, antihistamines prevent these symptoms.
