Well, Alan, the article may be more about a type of smoking than a type of smoking reduction but the benefit of one-hitters to the latter issue remains important.
You have reduced the number of pictures to 3 this seems to me unbalanced in that Smoking pipe (tobacco) is allowed to run on for over 23,000 bytes (all drawn from only 3 notes, 3 references, 5 external links) with 11 pictures compared to One-hitter (smoking) with under 4000 bytes and 3 pictures.  Factbase: I should google this first, but I think I saw an article stating that only 1% of the tobacco smokers worldwide use a pipe (compared with 5% cigar and 94% cigarettes); if 1/10 as many persons used cannabis as tobacco and 10% of cannabis users used a one-hitter, on that basis alone besides there being ethnic one-hitters used for tobacco too the articles should have equal length.
I think the value of the article depends partly on some information (particularly history) which is conveniently presented in picture captions; so how about I look into using the "gallery" approach which posts the pictures at the bottom of the article, smaller than the regular thumbnail kind but enlargeable.
