Does the limiting phrase "for purposes of this section" apply to marijuana products?

Further, the use of the limiting phrase "for purposes of this section" has been interpreted in other contexts not to limit the application of the relevant definition to that section only, see Johnson v. United States, 206 F.2d 806, 808 (9th Cir.1953), and there is no reason to believe a different conclusion should be reached when the word "chapter" is substituted for "section."

Finally, our precedent portends our holding today that "merchandise" under section 545 includes marijuana. Steiner v. United States, 229 F.2d 745, 747 & n. 5
