  11. Nervous System • Short-term effects • Changes take place in brain chemistry • Withdrawal symptoms • Heart Rate and BP increase • Long-term Effects • Increase risk of stroke due to decreased flow of Oxygen to the brain.

  12. Circulatory System • Short-Term Effects • Heart Rate increases • Energy reduced because less oxygen gets to the body tissues. • Long-term effects • Blood vessels are weakened and narrowed. • Cholesterol levels increase. • Blood vessels are clogged due to fatty buildup. • Oxygen flow to the heart is reduced • Risk of heart disease and stroke becomes greater.

  13. Respiratory System • Short-term Effects • Shortness of breath • Reduced energy • Coughing and coughing up phlegm (mucus). • Cold and flu are more frequent • Long-term effects • Risk of lung cancer & emphysema
