Totally avoidable if we never partake for the first time—even once

Similarly, even small acts of disobedience or minor failures to follow righteous practices can draw us down toward an outcome we have been warned to avoid. The Word of Wisdom provides an example of this. Likely the effect on the body of one cigarette or one drink of alcohol or one dose of another drug cannot be measured. But over time, the effect is powerful and may be irreversible. Remember the cracking of the sidewalk by the gradual small expansions of the root of the tree. One thing is certain, the terrible consequences of partaking of anything that can become addictive, like drugs that attack our bodies or pornographic material that degrades our thoughts, is totally avoidable if we never partake for the first time—even once.
