Second hand smoke is not only bad for people but has the same effects on our pets. Imagine now, if your pet ate your cigarette butt, nicotine patch, gum or swallowed the liquid from your e-cigarette! It takes about 1 cigarette or 1/2-1mg/lb for minor GI concerns to be seen. It would take between 5-11 cigarettes and 4mg/lb to be lethal. Please keep all nicotine products out of reach. Even the spit from chewing tobacco can be toxic!
